Just Enough Backups
What it is
Just Enough Backups is a free Fabric mod for Java Edition Minecraft that adds server-side world backups and an in-game workflow for managing them. It supports full, partial, and differential backups, with separate automatic schedules for each type and options to run them when a server starts or stops. Retention settings can keep a configured number of each backup type and optionally cap total backup size per world. In the backup browser, users can create, rename, delete, search, filter, and restore backups. A restore is prepared asynchronously; the server then shuts down so the restore can be applied safely at its next startup. Configurable multiple worker threads handle world scanning, ZIP compression, and restore extraction. Before creating a backup, the mod checks destination free space and aborts unless it meets twice the current world size plus the configured reserve. Mod Menu integration is optional. On dedicated servers, server settings must be edited in the server configuration file; the client config screen covers only HUD and preview settings. The project is MIT-licensed, and its listed latest release is version 1.2.0.7+26.3.
For and against
For
- Supports full, partial, and differential backups
- Schedules can vary by backup type
- Retention can include a per-world size cap
- Backup browser supports search and filtering
- Uses configurable multiple worker threads
Against
- Dedicated-server settings require editing the server configuration file
- Backups abort if destination space is insufficient
- Restore application waits until the next startup
The verdict
Just Enough Backups combines scheduling, retention, and an in-game management workflow for server-side worlds. Its storage check and configuration requirements are worth considering before setup.
Who it suits
This mod suits Java Edition Minecraft server operators who want scheduled, configurable world backups and an in-game browser. Dedicated-server operators should be comfortable editing the server configuration file.
